Here in Yosemite we have had people come from Jiuzhaigou as an exchange to discuss park management. I really like your first photograph. The water is unreal. I hope to one day visit myself.
Yes, it is a very beautiful place!
I was not very impressed with the way crowds were managed in Jiuzhaigou, but I guess that the mentality of a portion of the Chinese tourists themselves is a difficult problem to deal with. They make Paris subway look like an utterly polite place in comparison...
